The name Forever 21 also has a lot to do with the appeal. "To a young woman who can't legally drink yet, turning 21 is the dream. (To an older consumer, being trapped in a 21-year-old's body forever probably sounds horrifying.) But Forever 21 is aspirationally 21," as Liz Dunn, CEO of Talmage Advisors, put it to Business Insiderearlier this fall. Fascinating.
